@jesluimlatw JACOB P, TIRRRLL, OFtCIIARLBsTOwN, s. e. BRETT, OF sOMERvILLE, MASSACHU- sETTs, AssIeNORs vTO THRMsRLvEs, M. s. MARSHALL, AND HIRAMWHITNRY; AND sAID JACOB I .TIRRRLL AssIGNOR TO IIIRAM WHITNEY; AND sAID BRETT AssI'GNeR TO M.. s. MARSHALL.

town, and S. G. BRETT, of Somerville, both in the county ofMiddlesex, and State ofMassach usetts, have invented certainlmprovements ,in- Bi1l-Fi1es; and we hereby declare the following to be a full, clear, and exact description thereof, reference being had to theaeompaf nying drawings, in which Figure '1^ is a perspective view-of our file, with clamp holding papers.

.',Figure 2 is a perspective view of our iile, with clamp raised.

The'object of our invention is to'produee a tile for' filing papers, thatwill 'allow of' the removal of o ne paper without disturbing Other's,'-and. that firmly lhold papers without perforating' them. Y

. Our invention consists of a dat board, Of any suitable material, upon which the` papers to be led are" placed, and a' clasp, or clamp,- which is held u non the .paperby springs.

' -Inthe drawings-.- y

Ais a board, of suitable material', upon Awhich papers tobefilellareplaced.A "I 1." l B is a smaller board, adjusted over the board Af 1'. `-'L"Oth e centre'of B are attachedthe braces aand v'.'

These braces operate as hinges, turning, as they do, in-y sockets fast toB, in thezcentr Attached to .these hinges-0r braces' c and c', at m, are springs dand Thesespringsleoil around the braces c and c at m,

and then extend to A, where the ends are formed into, helical springs, and are there made ast in A at h.

The upper surface'of B is bevelled to the edge from the centre, so that-when B is raised, as shovming( 2, this bevelling allows the board B to come abovethe point of equal pressure by the springs on the sides, thus holding board B up, but a slight pressure upon. the upkper sidefof board B overcomes this-upward action of the springs d and d', and the board B comes downirmly upon the papers F, where it' holds them, by the ppos' ing action of the springs d and d. l

v'Elhe arms e and e','attached to B, serve to keep the papers in place.

i is a rin by which toraise board B. This Operation is simple and convenient, for'itallows of withdrawing papers witho'ut disturbing others.

' These files are cheaply made, andare very durable. Having fully described our invention,

, What we claim as new, and desire to secure by Letters Patent, is-

'lhe combination of board'B, hinges o and ,attachedto B,- a.'s described, springs d and d', arms e and e', and

'hoard A,-when these devices are constructed and arlranged ltoforni a bill-file, substantially as "described.
